hi, all. I have do some experiments using TinyOS2.x/Telosb. And the result makes me confused.
I changed the level of RF power by modifying the Makefile. As below: COMPONENT = MyDemoAppC CFLAGS += "-DCC2420_DEF_RFPOWER=1" include $(MAKERULES) After that, I wrote a small program to test it. Having changed RF power to 1, it will loses almost half the packets with a communication distance of half meter. At the same time ,the RSSI value of the received packets is about 45 dbm. However, when i set the RF power level back to 31, it delivery almost all packets when the RSSI value is 45 dbm. I don't know why.. PS: I read the RSSI value using "CC2420ActiveMessageC.CC2420Packet.getRssi()" Thank you for your any help!! Nathan
